Solution Overview

Problem

Existing spraying devices are limited in their ability to clean the bottom of a car tray due to a single spraying direction, making it difficult to effectively wash various equipment and automobile chassis in multiple directions.

Innovation Solution

A multi-directional spraying device with a frame component, spraying component, and moving component, featuring detachable first and second spraying mechanisms with movable nozzles, a valve component, and a water flow channel, allowing for adjustable and multi-directional spraying operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single spraying direction is used, then the device structure is simple, but the ability to clean the bottom of car tray and multi-directional surfaces is limited

Engineering Contradiction:

Improvespraying direction coverageVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spraying device is divided into multiple independent spraying mechanisms (first spraying mechanism on first wall, second spraying mechanism on second wall), each capable of spraying in different directions. This segmentation allows the device to cover multiple spraying directions simultaneously while maintaining relatively simple individual mechanism structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-direction spraying mechanism to a multi-dimensional spraying system by arranging spraying mechanisms on opposite walls (first wall and second wall) of the frame component. This spatial dimensionality change enables water to be sprayed in multiple directions (including upward and downward) simultaneously, greatly expanding the cleaning coverage area.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple spraying mechanisms are added, then multi-directional spraying capability is improved, but the device complexity increases

Engineering Contradiction:

Improvespraying mechanism flexibilityVSAvoidspraying component structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve component serves multiple functions: it controls water flow to both the first and second spraying mechanisms, can independently regulate each spraying mechanism, and can switch between different spraying modes. This multi-functionality reduces the need for separate control systems for each spraying mechanism, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple spraying mechanisms are merged into a single integrated system sharing common components including the valve component for water control, the water flow channel for fluid distribution, and the frame component for structural support. This merging approach allows multi-directional spraying capability while avoiding the complexity of completely separate systems.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of repair

If detachable spraying mechanisms are used, then ease of maintenance and assembly is improved, but connection reliability may be reduced

Engineering Contradiction:

Improvespraying mechanism assemblyVSAvoidconnection stability

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The spraying mechanisms are designed as detachable modules that can be independently removed and installed on the frame component. This segmentation enables easy maintenance, repair, and replacement of individual spraying mechanisms without affecting the entire system, while the modular design allows for standardized connection interfaces that maintain reliability.

Inventive Principle:

Principle #1Segmentation
